  • Patent number: 10389262
    Abstract: A device (2) for the on-demand commutation of an electrical current from a first line branch (14, 3; 36) to another, second line branch (4; 41; 71) is created, which has a number of power semiconductor switching elements (7; 47; 53), which are arranged in series and/or parallel to one another in the second line branch (4; 41; 71), and a control unit (18; 51) for controlling the number of power semiconductor switching elements (7; 47; 53). The control unit (18; 51) is adapted to apply to each of the number of power semiconductor switching elements (7; 47; 53) an increased control voltage (VGE) whose level is above the maximum permissible control voltage specified for continuous operation, in order to switch on or maintain the conduction of the number of power semiconductor switching elements and to cause an increased current flow through it, whose current rating is at least double the nominal operating current.
